Provenance Record

Well-structured 767-word News piece covering all key angles: what the trial involves, the phased rollout plan, labor context, known limitations, and an analytical closing section. Clear, neutral prose throughout. The 'What We Don't Know' section is a notable editorial strength — it honestly acknowledges the two-hour battery constraint and the underwhelming demo video rather than overselling the technology.

All five sources successfully snapshotted (source-0 through source-4, all HTTP 200). Sources read: source-0 (Interesting Engineering, Apr 28 2026), source-1 (Engadget, Apr 29 2026), source-2 (Futurism, May 1 2026), source-3 (New Atlas, May 1 2026), source-4 (Robotics and Automation News, Apr 30 2026). Core facts verified: G1 specs (1.32m, 35kg, 7.2km/h, up to 2h battery), $13,500 price (New Atlas), phased trial structure (Engadget), task expansion list (New Atlas), 60M+ Haneda passengers annually (confirmed IE, New Atlas, Futurism), 7M tourists in first two months of 2026 (confirmed IE and Futurism), Uchida quote verbatim (Futurism, original per BBC), Suzuki quote verbatim (Robotics and Automation News), humanoid form-factor rationale (Robotics and Automation News). Issue: The claim 'the highest-volume humanoid seller globally' is attributed to Interesting Engineering but does not appear in source-0. The description of Unitree as 'Hangzhou, China-based' also does not appear in any of the five sources. These appear to be background knowledge injected without source support.

All headline, summary, and lead claims are fully supported by the source snapshots. The single factual issue is a subordinate claim in the 'What We Know' section: the article describes Unitree as 'the Hangzhou, China-based manufacturer whose affordable platforms have made it the highest-volume humanoid seller globally, according to Interesting Engineering' — neither the Hangzhou geography nor the market-leadership assertion appears in the IE snapshot or any other captured source. This can be honestly covered by a corrections note.

Strong, well-sourced coverage of a newsworthy aviation robotics deployment. One subordinate unsourced assertion about Unitree's market position warrants an APPROVE_WITH_CORRECTIONS verdict. The rest of the article is accurate and publication-ready.
